Default New to nitro


I need help. I just got a new Losi 8ight 2.0. Im new at nitro so bare with me.

The engine i selected was the novarossi p5xst. My first question is this:

When i go to install this, the mount that connects the throttle servo to the engine is on the opposite side from what i see in the pics. It is closest to the pipe.

That does not seem right? Is there a way to switch that??? Im lost there.

Also, what pipe do you guys suggest i use with this motor?

Lastly, when i have the motor out and holding in my hand and i try and rotate the crankshaft, it does not go all the way around. Now i assume this is due to the compression build up but tell me im right before I bust something!

Again, thanks in advance for any responses.

there is a screw in the motor case at the base of the carb, carfully loosen it and flip the carb 180 is ur engine it is the flat head screw you see....loosen it and you can move the carb to where u need it it could still be tight after you loosen the screw but it has to be turned around....

also you want to turn the carb to the point the linkage is pulling in as clos to straight line as possible, the carb wont be square to the motor it will be turrned a few deg im shure.....

the piston sleve are made to get tighter as the piston reaches the top of the stroke, so when the engine is up to temp the fit is perfect......the first couple times you run it or some ppl do it all the time is heat up the motor with a heat gun or hair dryer before you try to start it.

sorry ive never ran this motor so i cant help on the pipe......

Thank you for that. Also, that red thing in the top of the carb, does that stay in?

That is a carb venturi, it's a tuning tool. You can limit the air flow into the engine so you can actually decrease some power and get long run time. You'll see that on really loose tracks where people don't want to lay down all the power. If you're new run the smallest venturi you can get for that engine, less power and longer run time is good if you're learning.

I just ordered the same engine except this ones modded by hot mods and has ceramic bearings. Cant wait to get it and run it. I was told the jp3, Novarossi 9886 = ofna 086 ( i guess there the same pipe) but rated #1 pipes for this engine. I am gunna run a 053 and axe rossi 2050. I will have to see which 1 i like better at the track. I have to wait another month before the weather lets me run it so when you get your let me know how it runs!!!
